IMPROVEMENT IN COMBINATION LOCKS.

Speciication forming part of Letters Patent No. 119,948, dated October 17, 1871.

To all Iwhom it may concern:

Beit known that I, GEORGE H. PEAoocK, of Webster, in the county of Monroe and State of New York, have invented certain Improvements in Per-mutation Locks, 'of which the following is a speciiication:

My invention consists in the combination ot' the bolt, lever, and finger-bars in such a manner that the said bolt shall be thrown back by the proper manipulation of/the said linger-bars. The object of my invention is to provide a readilyadjusted guard, which shall admit of being speedily opened by the operation of theI tin gers when kno wing the order in which the finger-bars stand.

Figure l is a front view of the working parts, showing the bolt thrown up. Fig. 2 is a sectional View on the line .r .r of Fig. 1. Fig. 3 is a front view of the working parts, showing the bolt withdrawn. Fig. 4 is a sectional view on the line y g/ of Fig. 3. Fig. 5 is a side view of the lever and one of the nger-bars.

The self-locking'bolt A is thrown up by the S-shaped spring B, and forcedback by the pressure of the lower `part of the cross-plate C against its (the bolts) incline or sloping heel X, Fig. 2, said cross-plate.constituting the perpendicular arm of a bent lever, having its fulcrum at the angle and its horizontal arm or armsD proj ecting above and across the tops ofthe ringer-bars E E E and E. The upward pressure of the finger-bar E brings it against and tends to elevate the` outer end of the said horizontal arm D, Fig. 3, thereby pressing the lower end of the said perpendicular arm or cross-plate O, Fig. 4, against the said sloping heel X, thus sliding back the said bolt A. Guards F F project from the lower part of the said cross-plate C at nearly right angles, and against the face of the said inger-bars E E E and E', thus preventing the movement of the lever, and, consequently, ofthe bolt A. Slots or gains G G; are provided in the sides ot' each of the linger-bars E E E and E at different elevations. Vhen by the proper manipulation of the said ringer-bars EE E and E the slots or gains G, standing underneath the guards F F, are brought in a horizontal line in front of the said guards F F the bent lever, consisting ofthe said cross-plate O and arms D, may be moved by the upward pressure of the finger-bar E against the outer end of one of the arms D, and, by elevating the same, produce a pressure of the lower part of the cross-plate C against the sloping heel X, thus sliding back the bolt A, Fig. 3. The finger-bars E E E and E are each formed with their opposite sides or faces alike, thus making them reversible. There is also on each side of the said finger-bars E E E a shoulder, H, Fig'. 5,

which rests on the bearing I when the said tin- 1 ger-bars are not elevated, and which are brought up against the upper bearings J J when at their greatest height, at which time the tops of the lingerbars E E E are in contact with the ends of the arms D, but prevented from elevating the said arms by the shoulder H. The finger-bar E has no shoulders, hence, when the ringer-bars E E E are put in proper position for the entrance of the guards F F into the slots or gains G, the said linger-bar E may be raised to a greater height than the finger-bars E E E, Fig'. 3, thus moving the lever and thereby sliding back the bolt A. By sinking the faces of the finger-bars E below the slot G, as at K, Fig. 5, the guard F will not press against the said sink or indenture K, but will allow the said finger-bars E to drop back, so that the shoulder above the said slot or gain G will lodge on the end of the guard F, leaving the slot G to be entered by the guard F. Numbers 1 2 v3y et 5 6 7 8 are placed. on the faces ofthe iinger-bars E E E and E to indicate their required movement. Figures 1 2 3 4, Fig. 1, are placed on the lower part of the cross-plate C to indicate the proper numbers on the linger-bars. The opposite faces of the finger-bars E E E and E are numbered alike; hence any number on them may be made to stand under any number on the cross-plate.

I claim as my inventionl. The bolt A having the incline X, and the lever consisting of the cross-plate C and arms D, in combination with the finger-bars E E E and E substantially as and for the purpose set forth.

2. The bolt A having the incline X, spring B, cross-plate C, arms D, and guards F, in combination with the finger-bars E E E and E provided with slots G G, shoulders H H, and indentures K, substantially as and for the purposes set forth.
